VALVE.

SPECIFICATION forming part of Letters Patent No. 311,833, dated February 3, 1885.

Application filed April 7, 1884.

To 0. whom it may concern.-

Be it known that I, BENJAMIN W. HOXIE, of Hartford, Connecticut, have invented a new and useful Valve, of which the following description and claims constitute the specification, and which is illustrated by the accompa nying sheet of drawings,

This valve has two distinguishing characteristics. First, it revolves under the'action of the passing fluid in a peculiar manner; second, it indicates externally whether it is open or closed.

Figure 1 is an external side View of the apparatus. Fig. 2 is a view of theleft-hand end of the same. Fig. 3 is a central longitudinal section on the line X X of Fig. 2. Fig. 4 is a central crosssection on line Z Z of Fig. 1. Fig. 5 is a side view of the perforated disk G.

A is the exterior shell. It has the openings B, C, and D, all of which have screwthreads for the reception of conduitpipes. The cap E is screwed into the opening D in Figs. 1 and 3, leaving the opening 0 for the reception of the outlet-pipe and the opening B for the reception of the inlet-pipe; but the cap may be screwed into the opening C, leaving the opening D for the reception of the outlet-pipe. The shell A also has the annular valve-seat F, and is furnished with the perforated disk G, which latter is screwed int-o the opening D in advance of the cap E. The valve proper consists of the disk II, the inclined wings I, J, K, and L, and the stem M. The left-hand part of the stem has its surface cut into the form of a circularrack, N. The righthand part of the stem is encircled by a spiral spring, 0, which works between the annular shoulder P on the stem and the perforated disk G. The extreme right-hand end of the stem revolves in the central perforation of that disk. The rack N works the pinion Q. That pinion is keyed to the shaft R, and that shaft passes through the stuffing-box S to the exterior of the shell A. On its outside end the shaft R is provided with a pointer, T, which (No model.)

I oscillates on the face of the dial 'U, and which is protected from harm by the glass disk V, held in place by the annular gland NV.

The mode of operation is as follows. Fluid passing into the apparatus from the inlet-pipe forces the valve back from its seat against the action of the spring 0. That backward motion is communicated to the pinion Q and shaft R, and thus to the pointer T, causing the latter to indicate the fact that the valveis open. So, also, the action of the fluid in passing through the valve causes the valve to revolve with the stem M, inasmuch asthe wings I, J, K, and L are inclined, as shown in the drawings, and are therefore operated upon by the passing fluid much as the floats of a windmill are opis screwed into the opening D, the fluid passes out through the opening C; but if the cap is screwed into the latter, then the fluid passes through the four outer perforations of the disk G, and thence through the opening D. If the constructer prefers, he may omit one or the other of the last-named openings. When the valve is used in the inlet-pipe of a steanr boiler or other locality where there is a sufficiently strong backward pressure of steam or other fluid to close the valve without the aid of the spring 0, that spring may be omitted.

I disclaim the invention shown in Letters Patent of the United States No. 160,640, grant provement in valves for street water-mains.

I claim as my invention The valve H, having the stem M, provided with the rack N, in combination with the pinion Q, the shaft R, and an external inclicator, substantially as described, and for the purpose set forth.
